What our clients say

There’s a reason Culligan of Central Ontario is the best water treatment company in Central Ontario with over 4.2-Stars Google Reviews.

We had a great experience with Matt from Culligan purchasing and right through the installation of our tankless reverse osmosis water system. Matt checked in and came to make sure we didn’t have any questions after installation and that the system was running well. We couldn’t ask for more.
We recently upgraded our home’s water system with Culligan’s water softener and filtration setup, and the experience has been outstanding from start to finish. Matthew did an excellent job guiding us through the selection process, helping us choose the ideal system for our needs. His professionalism, product knowledge, and support after the purchase have been exceptional.Before installing the system, our stainless‑steel water bottle would develop an unpleasant smell after just one day. Since switching to Culligan, there is no smell at all, and the water tastes absolutely fantastic. The difference is truly noticeable.We’ve also experienced improvements beyond drinking water, our hair and skin feel much softer, which has been a welcome bonus we didn’t fully expect.Overall, we couldn’t be happier with the quality of the product and the exceptional service we received. Highly recommended!
Matthew from Culligan was fantastic to work with. He was kind, responsive, flexible and extremely helpful from start to finish. He clearly laid out all my options and answered all of my questions, was resourceful and solution-oriented, and followed through exactly as promised. A genuinely great end-to-end service experience — highly recommend.
I would like to thank Matthew from Culligan water for his advice on our water issues as he suggested we get a uv light and a water filter which took care of our problems would highly recommend him for being very professional and friendly.
My experience with MATTHEW was fantastic. We contacted him through the office, and he immediately got back to us after our water filtration system started to act up after 20 plus years. Matthew sent me pics of what he had in mind, my wife and I looked them over and chose the system he suggested. He kept in touch throughout the whole process, including a follow up after the installation. His tech that installed it was also great, performing the job and leaving the place just as he had found it. We have always dealt with Culligan for our water filtration system, including replacement filters. We also have dealt with them for our water Sofener and the salt delivered every couple of months. Thanks Matthew for all your attention to our needs and all details in getting the job done correctly.
Very friendly and helpful staff. Easy to go in and pick up the part I needed. Tons of parking and easily accessible location.
I had been wanting to improve the water in my home for years, but it wasn’t until I saw how much our hard water was impacting our kitchen and bathroom renovations that I finally decided to upgrade to soft water with Culligan. I’m so glad I did. The difference has been huge. No more water marks or hard water stains on our faucets, and everything (including the dishwasher) stays noticeably cleaner. My hair and skin have improved drastically since switching and don’t have to use half the conditioner bottle on my hair anymore.Working with Matthew made the whole process even better. He was kind, funny, and incredibly knowledgeable. He listened to my concerns, didn’t oversell, and simply educated me on what system would be best for my needs. Overall, such a great experience. I highly recommend Culligan, and especially Matthew!
Matthew was great and was present for the installation, making sure tech knew our requirments
Matthew was very informative. He came back after installation and there was a little issue with the water. He reset the system. Came back and tested the water and all good now. Excellent service. 😁👍
We had the pleasure of dealing with Matthew from Culligan. He was very nice, explained everything in detail and spent lots of time testing my water. He was very knowledgable and great at explaining every detail.He visited us after the install to re test the water which is a great service that most companies don’t do.I would highly recommend you deal with Matthew if you are sourcing a water system.
We chose Culligan primarily because they are willing and able to deliver and bring salt inside and put it in our tank. Matt was helpful with getting us set up. Thank you
Matthew is amazing- assisting the initial installation 2 years agoHe is still available for any support
One day recently I noticed our water was brown. Called Culligan and there were here within 2 days. Sample of our water was taken and it was very high with iron. Matthew was here the next day and suggested we get a Big Blue Filter. We had it installed, the next day Matthew dropped by to show me how to change the filter. He opened the filter and it was already brown from the iron.Thank you Matthew and all the staff for being prompt to resolve our water problem.
We were looking to cancel our service but Matthew came and tested our water and provided the best option for our needs. Old fashioned service which does happen much anymore. Daniel did an amazing job of the installation. Thank you to both for this and we will remain a loyal client with Culligan.
Great water so far!Matthew was super knowledgeable and provided great service.
We had a great experience with Culligan Barrie! Matthew, the sales representative, was amazing, knowledgeable, patient, and very helpful throughout the process. He also met our timelines and was extremely accommodating! Kyle, the installer, was professional, friendly, and efficient. Since the installation, our water tastes fantastic, and we’re so happy to have this system in our new home and thankful for the peace of mind! Highly recommend Culligan Barrie and their team!
Great experience. Old water softener was not working. Some highly knowledgeable staff were able to guide us in the proper direction. Now we have some solid water !! Not too solid tho now that there is less calcium in it!! Thanks Matthew for the guidance and support.
Matthew was my service techVery sufficient polite, cleans up after he is done and always on timeVery happy with his service
A few years ago, I was actively shopping around for a comprehensive water treatment solution for my home. I had several different companies come in to quote and explain their systems, but honestly, none of them inspired confidence. I found that their explanations were vague, and I was left feeling uncomfortable and uncertain about what I was actually buying or how it worked.That all changed when I met Matthew from Culligan Water.From the start, Matthew was a breath of fresh air. He took the time to explain everything—and I mean everything—in detail. He broke down exactly what the treatment process involved, how the equipment functioned, and why it was the right fit for my specific water quality issues. I finally became absolutely comfortable and confident in making a significant investment in my home's water.We initially started with a Culligan Carbon Filter, and the improvement was immediate for drinking water quality. After a year, I didn't hesitate to call Matthew back when the hard water in our area was getting a little bit too rough on our skin. We chose to also purchase a Culligan SMART Softener, and the combined results have been nothing short of amazing. The overall water quality and feel in our home is vastly improved.Beyond the superb products, the service is equally excellent. Right after our installation, we needed to call back for an adjustment, and Matthew and the entire Culligan team were incredibly responsive, friendly, and accommodating.I highly recommend Matthew and Culligan Water to anyone considering water treatment. You will get expert advice, superior equipment, and unmatched service.
Thanks to Matthew, purchasing my Culligan water softener was an easy decision. Matthew is knowledgeable, provides all the options and does not pressure you into getting anything. Matthew provides education regarding water treatment systems and answers all questions in a professional manner. Matthew attended when my softener was installed, assisting when needed to ensure it went smoothly. His follow up is next to none! I have never experienced follow up after my installation like I have with Matthew. Culligan in Barrie is lucky to have him on staff!
We had the pleasure of working with Matthew on our first installation of our water softener and carbon filter 5 years ago. We really enjoyed our water over the years and last month when we moved we contacted him again for our new house. He did not disappoint. Together we were able to figure out how to make it work for us and we’re very happy!! Thanks again Matthew!!
Amazing work by this team! Thank you! Matthew was great and really helped us out!
I had an excellent experience working with Matthew from Culligan Water. He was knowledgeable, patient, and genuinely went out of his way to make sure I understood everything about my system. From recommending the right salt and filters to explaining how the equipment works, he made the whole process incredibly easy and stress-free.Matthew’s customer service stood out — he was friendly, responsive, and took the time to answer all my questions without rushing. It’s rare to meet someone who combines expertise with such a sincere, helpful attitude.Overall, I feel very confident about my water system now, and that’s hugely thanks to his support. Highly recommend Matthew to anyone looking for professional, trustworthy service from Culligan.
Matthew from Culligan in Barrie was awesome! Very helpful and a great communicator!
We bought a home this summer that had a well. We weren't keen on the iron content and the odor. After placing a call to Culligan in Barrie (home had a Culligan water system in it) they sent a technician out to look at the system and update filters. We expressed an interest in an iron filter. Matthew came out to the house and was so informative. He explained how the current system worked and showed us with chemical testing how much iron was in our system and it was an iron filter that was required. We had the iron filter installed and today was Matthew's follow up appointment. He again was so informative and showed what our water was testing at compared to before the iron filter. We are so pleased with Culligan Barrie and their service. Highly recommend them and Matthew.Paula and Jason Williams Keswick Ontario
Matt was extremely helpful and communicated all instructions on equipment very well. Many thanks.
I am very pleased with the new water treatment set up. Matt has provided excellent service and the installation looks much better than the plumbing before hand. Thank you Culligan
Outstanding Water Softener & Exceptional Service!I recently had a Culligan water softener installed, and the results have exceeded my expectations. The water feels noticeably softer, there are no more hard water stains, and even my dishes and laundry look cleaner. It’s made a real difference in our daily routine and overall home comfort.A big shout-out to Mathew, who provided truly exceptional service. He was knowledgeable, patient, and walked me through every detail—from choosing the right system to explaining how it works. His professionalism and friendly attitude made the entire experience smooth and stress-free.If you’re considering a water softener, I highly recommend going with Culligan and asking for Mathew. You won’t be disappointed!
Thank you Matthew from Culligan Barrie! He was super friendly, professional and thorough. Matthew went above and beyond to sort out all our well water issues. The Smart products he recommended are working great to make sure our water stays soft, odourless and clear! Highly recommend.
We now have excellent water, and are very happy thanks to Matthew!
5 Stars to Matthew of Culligan Barrie! Superior service and education regarding a new install we recently had completed!
I can’t say enough about the excellent service we received from Culligan. Matthew was outstanding — he took the time to educate us on our water, explained how the water softener and RO system work, and answered all of our questions in detail. He came back during the installation to ensure everything was done properly. We are very happy with our new water system and would definitely recommend Culligan Barrie.
Matthew was very helpful and accommodating. Great customer service and support! Installed a UV filter and disinfected my system. Gave me good tips/advice on my filter and softener. Looking forward to clean water!
I noticed a real difference in my water quality after the service! The work was done quickly and professionally. Shaun Whelan was great to deal with, very knowledgeable and friendly. Excellent experience overall, highly recommend!
We recently had a Culligan water softener and purifier installed, and I couldn’t be happier with the results. The difference in our water quality was noticeable right away — cleaner, softer water throughout the house and great-tasting drinking water.A big part of the great experience was thanks to Matthew, who handled the installation. He was incredibly professional, knowledgeable, and courteous from start to finish. He took the time to explain how everything worked, answered all my questions patiently, and made sure the setup was neat and tidy before leaving. It’s rare these days to see that level of care and attention to detail.If you’re considering a water softener or filtration system, I highly recommend Culligan — and be sure to ask for Matthew. Outstanding service and an even better product!
We had a wonderful experience with Matthew. . He was very polite, took his time to explain everything to us. He phoned us to make sure that the installation went well and then followed up to make sure the softener was doing its job. This gentleman is knowledgeable, polite and very patient. I would highly recommend him to anyone. It was a pleasure dealing with him.
I’m very grateful for the service provided by Matthew ; he is extremely polite, kind, and competent. This is my first house, and he helped me with all my questions. Now we have the best water to for use, including for drinking . I’m very happy! Thank you. 👏🏻👏🏻👏🏻☺️🥰

Matthew is consultant for the water softener system. He has explained and demonstrated the best quality water softener system which gave us a green light of the good water. We are experiencing the difference.I appreciate for his professionalism and impersonal skills.
Matthew was a nice and helpful guy .He was very knowledgeable .we purchased the Smart HE water softener and carbon filter combo. So far very happy with the system and service.
Love my new water filtration system ❤️. Matt was very informative, helpful and very personable, he answered all my questions and showed me how everything works and how to maintain it in the future. I highly recommend 👌
Mathew knows what we need and follows it from signings to install to setup up to older tank removal. 👍
We got our reverse osmosis system installed about 2 months ago. We met with Matthew, who was one of the most knowledgeable and sincere salesperson we had ever met. He spent a lot of time with us explaining water quality, explaining the quality of water from the lake, the quality of water that we buy and the quality of various different bottled waters and of course the quality of water from Culligan. He was extremely knowledgeable like I said and explained everything so that we could all understand what he was talking about. We had the system installed within a week and have been absolutely thrilled with it. Our water quality now is amazing And it really tastes fresh and clean. Would highly recommend Culligan Barrie, be sure to ask for Matthew! Hey Culligan Man! Lol, couldn't resist. 😁 Also I should add that the installation process was very precise and clean. We are thrilled we no longer have to purchase drinking water.
Shout out to Shaun and Keith!After doing some research on water softeners and filtration systems, we came across the Culligan website. Shaun was incredibly helpful , he tested our water, identified the issues, and gave us clear instructions and the right tools to make our water perfect. He explained everything thoroughly and delivered exactly what he promised. The installation process and choice of units worked out perfectly for our needs.Thank you, Shaun and Keith, for your excellent service and professionalism! Highly recommended.
It was a pleasure working with Mathew. He took the time to explain our challenges and quickly came up with solutions for our new home. He is very knowledgeable and never pushed us to purchase anything he felt we didn’t need. Installing a new water softener, reverse osmosis system, and iron tank was exactly what we needed as we use well water.

Usually, if your water smells like sulfur or rotten eggs, the reason is because your water has high Hydrogen Sulfide (H2S) content.

H2S is a gas that is released from the earth and finds its way into groundwater. It’s especially common in well water located near shale, sandstone, coal, peat, or oil.

(Occasionally, a rotten-egg smell in your water could also be caused by a water heater or by sewage pollution in your water. If you’re on city water, the most likely explanation is your water heater.)

A rotten-egg smell in your water may be strongest right after turning the water on, as heat forces the gas out of the water and into the air
H2S dissolves in water to create a weak acid that can corrode metal pipes

Negative Effects of H2S

In addition to potential health risks, having H2S in your water can cause all sorts of annoying problems. H2S in your water can:

  • Cause coffee and tea to be discolored and taste funny
  • Corrode metals (steel, copper, iron, brass), including silverware
  • Cause foods cooked with water to taste “off”
  • Create yellow or black stains in your bathroom and kitchen 

How Do You Fix It?

Here at Culligan, you can find everything you need to get rid of H2S and that sulfur/rotten-egg smell from your water.

The first step we have to take is to test your water, so we can be sure of the real cause of the rotten-egg smell.

Fortunately, here at Culligan we offer this service free. One of our water experts will come to your home to test the water (you can’t send it away to a laboratory because H2S is a gas and could dissipate during transport) and let you know the source of your rotten-egg smell. You’re under no obligation whatsoever. 

Culligan water treatment systems can completely remove the rotten-egg smell from your water
